Carbohydrate scaffolds in chemical genetic studies

Area of Science:

• Carbohydrate chemistry
• Systems biology
• Chemical biology

Background:

• Small molecules modulate protein function, aiding systems biology research.
• Carbohydrates are valuable scaffolds for generating bioactive compounds due to their recognition properties.

Purpose of the Study:

• To report the design, synthesis, and biological evaluation of carbohydrate-based inhibitors and protein ligands.
• To demonstrate the utility of carbohydrates as scaffolds for combinatorial library synthesis.

Main Methods:

• Design and synthesis of carbohydrate-based small molecules.
• Biological assays to evaluate inhibitory or ligand activity.
• Nuclear Magnetic Resonance (NMR) spectroscopy to determine binding affinity and interaction topology.

Main Results:

• Successful design and synthesis of various carbohydrate-based inhibitors and ligands.
• NMR analysis confirmed molecular binding, quantified affinity, and defined interaction modes.
• Demonstrated solid-phase combinatorial synthesis of a 37-compound carbohydrate library.

Conclusions:

• Carbohydrates are ideal scaffolds for developing bioactive molecules and combinatorial libraries.
• NMR is a powerful tool for characterizing small molecule-protein interactions and guiding inhibitor design.
• This approach enhances understanding of biological recognition and facilitates drug discovery.
